EDIT:
In case i didn't read the question carefully, if you want to only get function parameters,you can see these example :
$content_file = 'function func_name($param_1=\'\',$param_2=\'\'){';
preg_match('/function func_name\((.*)\{/',$content_file,$match_case);
print_r($match_case);
but if you want to manipulate the function, read below.
How about these :
- read file using
file_get_contents();
- use
preg_match_all();
to get all function inside that file.
- please not that i write
/*[new_function]*/
inside that file to identify EOF.
I use this to dynamically add/ delete function without have to open that php files.
Practically, it should be like this :
//I use codeigniter read_file(); function to read the file.
//$content_file = read_file('path_to/some_php_file.php');
//i dont know whether these line below will work.
$content_file = file_get_content('path_to/some_php_file.php');
//get all function inside php file.
preg_match_all('/function (.*)\(/',$content_file,$match_case);
//
//function name u want to get
$search_f_name = 'some_function_name';
//
for($i=0;$i<count($match_case[1]);$i++){
if(trim($match_case[1][$i]) == $search_f_name){
break;
}
}
//get end position by using next function start position
if($i!=count($match_case[1])-1){
$next_function= $match_case[1][$i+1];
$get_end_pos = strripos($content_file,'function '.$next_function);
} else {
//Please not that i write /*[new_function]*/ at the end of my php file
//before php closing tag ( ?> ) to identify EOF.
$get_end_pos = strripos($content_file,'/*[new_function]*/');
}
//get start position
$get_pos = strripos($content_file,'function '.$search_f_name);
//get function string
$func_string = substr($content_file,$get_pos,$get_end_pos-$get_pos);
you can do echo $func_string;
to know whether these code is running well or not.
